MATLAB: Error using fdesign.notch

Question

I'm trying to test the notch filter code referenced here, https://www.mathworks.com/help/dsp/ref/fdesign.notch.html.

F0 = 60;   % interference is at 60 Hz
Fs = 3000; % sampling frequency is 3000 Hz
notchspec = fdesign.notch('N,F0,Q',2,F0,10,Fs);
notchfilt = design(notchspec,'SystemObject',true);
fvtool(notchfilt,'Color','white');

I have the Signal Processing Toolbox but I'm getting the error below.

Unable to resolve the name fdesign.notch.

Signal Processing Toolbox Version 8.5 (R2020b)

Answer 1

The fdesign.notch function is in the DSP System Toolbox.

An appropriate Signal Processing Toolbox equivalent function is bandstop.
